5.2 Cleaning the Oil Cooler
Switch the pump off and ensure that it can not be started up inadvertently.
When blowing out with compressed air, protect your eyes and wear pro-
tective goggles.
Regularly check the oil cooler to see if it has accumulated dirt.
The interval between the regular checks will depend on the ambient condi-
tions and the process in each case and needs to be defined based on expe-
rience gained during operation.
For this run a visual inspection through the inspection opening on top of the
cooling unit, see fig. 5.1.
A dirty cooler may cause increased oil and pump temperatures and impair
operation and reduce the service life of the pump.
With the pump at standstill, the fan’s housing may be opened so as to clean
the oil cooler.
Open the fan’s housing and clean the cooler with compressed air from the
accessible side.
If it is not possible to stop the pump, then in such a case the cooler may, if
required, be cleaned from the top through the inspection opening using a
vacuum cleaner.
5.3 Draining Out Condensate
(optional)
To drain the condensate out, the pump must be separated from the pro-
cess by a valve. Please note that process gases and condensate may pre-
sent a hazard to health.
The optional silencer (P/N 119 002) has a condensate drain. Possibly present
liquid which has collected in the silencer can be drained out through the con-
densate drain.
The silencer must be checked regularly especially if much condensate is col-
lected. Drain out condensate if required.
The interval between the regular checks will depend on the ambient condi-
tions and the process in each case and needs to be defined based on expe-
rience gained during operation.
5.4 Cleaning the Dust Filter in the Intake Line
(optional)
The dust filters which are installed upstream of the pump need to be checked
regularly for contamination and cleaned as required.
